Neuromidin is an anticholinesterase agent that has a direct effect on the functions of the central nervous system. It is used to treat various diseases of the nervous system, including those caused by injuries. Pharmacological action develops quickly. The drug is prescribed for adults and children over 14 years of age.

Interactions with other medications
Neuromidin may also interact with other medications. It enhances its sedative effect if used with drugs that depress the central nervous system, such as sleeping pills, tranquilizers from the benzodiazepine group, or together with barbiturates. Let us recall that a well-known representative of barbiturates, phenobarbital, is included in Valocordin and Corvalol, which are sold without a prescription. If you combine Neuromidin with beta-blockers, which reduce the heart rate and heart function, there is a risk of bradycardia, collapse and fainting.

Mechanism of action of the drug
It is known that the nerves give the order to the muscles to contract, acetylcholine, which is released into the synaptic cleft - the place where the nerve connects with the muscle. Acetylcholine, if not removed in time, will keep the muscle in prolonged contraction. Therefore, “cleaning” the synaptic cleft from acetylcholine is very important, and this is done by the enzyme acetylcholinesterase. So, Neuromidin inhibits it, and acetylcholine circulates longer in the synaptic cleft, and the impulse becomes brighter, longer, more active. It affects the level of potassium channels. As a result, neuromuscular transmission and smooth muscle contractility improve.
Pharmacodynamics
Neuromidin® has a direct stimulating effect on the conduction of impulses along nerve fibers, interneuronal and neuromuscular synapses of the central nervous system and the peripheral nervous system. The pharmacological action of Neuromidin® is based on a combination of two mechanisms of action: blockade of potassium channels in the membrane of neurons and muscle cells; reversible inhibition of cholinesterase at synapses.
Neuromidin® enhances the effect on smooth muscles of not only acetylcholine, but also adrenaline, serotonin, histamine and oxytocin.
Neuromidin® has the following pharmacological effects:
– improves and stimulates impulse conduction in the nervous system and neuromuscular transmission;
- enhances the contractility of smooth muscle organs under the influence of agonists of acetylcholine, adrenaline, serotonin, histamine and oxytocin receptors, with the exception of potassium chloride;
- improves memory, inhibits the progressive course of dementia.
In preclinical studies, Neuromidin® did not have teratogenic, embryotoxic, mutagenic, carcinogenic or immunotoxic effects, and did not affect the endocrine system.
Pharmacological properties of the drug Neuromidin
The action of ipidacrine (9 amino-2,3,5,6,7,8-hexahydro-1 H-cyclopentane (b) quinoline hydrochloride monohydrate) is due to a biologically beneficial combination of two molecular effects - blockade of potassium membrane permeability and reversible inhibition of cholinesterase activity. In this case, blockade of potassium permeability of the membrane plays a leading role. Blockade of potassium permeability of the membrane leads primarily to an increase in the repolarization phase of the action potential of the excited membrane and an increase in the activity of the presynaptic axon. This leads to an increase in the entry of calcium ions into the presynaptic terminal, which in turn leads to an increase in the release of transmitter into the synaptic cleft at all synapses. An increase in the concentration of the transmitter in the synaptic cleft promotes stronger stimulation of the postsynaptic cell due to the mediator-receptor interaction. In cholinergic synapses, inhibition of cholinesterase causes even greater accumulation of the neurotransmitter in the synaptic cleft and increased functional activity of the postsynaptic cell (contraction, conduction of excitation). Neuromidin enhances the effect of acetylcholine, adrenaline, serotonin, histamine and oxytocin on smooth muscles. The drug has the following pharmacological effects: stimulation and restoration of neuromuscular transmission; restoration of impulse conduction in the peripheral nervous system after its blockade by various agents (trauma, inflammation, exposure to local anesthetics, some antibiotics, potassium chloride and other factors); increased contractility of smooth muscle organs; specific moderate stimulation of the central nervous system with individual manifestations of sedation; improvement of memory and learning; analgesic and antiarrhythmic effect. The drug does not have teratogenic, embryotoxic, mutagenic and carcinogenic, as well as allergenic and immunotoxic effects, and does not affect the endocrine system. Rapidly absorbed after oral administration. The maximum concentration in blood plasma is observed 1 hour after oral administration and 25–30 minutes after subcutaneous or intramuscular administration. From the blood, the drug quickly enters the tissues and at the steady state stage, only 2% of the drug is detected in the blood serum. The half-life in the distribution phase is 40 minutes. The degree of binding to blood proteins is about 40–50%. Absorbed predominantly in the duodenum, to a lesser extent in the jejunum and ileum, only 3% of the dose is absorbed in the stomach. Elimination from the body is carried out through a combination of renal and extrarenal mechanisms (biotransformation, excretion in bile), with excretion in urine predominating. Only 3.7% of the drug is excreted unchanged in the urine, which indicates its rapid metabolism in the body.
Pharmacokinetics
After oral administration, intramuscular and subcutaneous administration, it is rapidly absorbed. Cmax in blood plasma is achieved 1 hour after oral administration and 25–30 minutes after intramuscular or subcutaneous administration. Binding to blood plasma proteins is 40–50% of the active substance. It quickly enters the tissues, the half-life of distribution is 40 minutes. Metabolized in the liver. It is excreted through the kidneys (mainly by tubular secretion and only 1/3 by glomerular filtration) and extrarenally (through the gastrointestinal tract). T1/2 of Neuromidin® when administered parenterally is 2–3 hours. After parenteral administration, 34.8% of the drug dose is excreted unchanged in the urine.

M-cholinomimetics and other cholinesterase inhibitors increase the effect and side effects (the risk of a cholinergic crisis increases, especially in patients with myasthenia gravis). Beta-blockers cause bradycardia if they were used before treatment with Neuromidin. When used simultaneously with alcohol, adverse side effects may increase. Special instructions The drug increases the muscle tone of the uterus and can cause premature labor. Caution should be used for stomach ulcers, thyrotoxicosis, and diseases of the cardiovascular system. The drug penetrates well into tissues and organs, incl. brain and may have a sedative effect. Care should be taken when working with machinery. During treatment you should not drink alcohol. Storage conditions List A. In a place protected from light, at a temperature not exceeding 25 °C.
Side effects
Caused by stimulation of m-cholinergic receptors: salivation, increased sweating, palpitations, nausea, diarrhea, jaundice, bradycardia, epigastric pain, increased secretion of bronchial secretions, bronchospasm, convulsions. Salivation and bradycardia can be reduced with m-anticholinergic drugs (atropine, etc.). Increased uterine tone, allergic skin reactions.
Rarely (after using higher doses), dizziness, headache, chest pain, vomiting, general weakness, drowsiness, and skin reactions (itching, rash) were observed. In these cases, reduce the dose or interrupt the drug for a short time (for 1–2 days). These side effects are observed in less than 10% of patients.
Modern spinal neurosurgery
Only modern minimally invasive surgical intervention (for example, video endoscopic microdiscectomy, or laser vaporization and nucleoplasty) can remove the hernia defect itself, or prevent its appearance in the case of protrusion. However, the Russian patient knows very well what surgery is. It hurts. This takes you out of normal life for a long time. It may be dangerous. There are so many such “buts” that surgery is considered the last type of treatment, when massage therapists, carboxytherapy sessions, manual therapists and kinesiotherapists stop helping.
Fortunately, in European countries, Israel, and the USA, the approach is completely different. If there are indications, the patient is operated on without pain, and often leaves the hospital on his own feet on the same day or the next. His quality of life is preserved. He is not prohibited from sitting for many days, and he is not forced to relieve himself while standing. Therefore, modern surgery is considered the best, fastest and most effective means of radical treatment. By the way, doctors in many Eastern European countries, for example, the Czech Republic, show excellent results in treating hernias surgically at fairly modest costs.
In Russia, they prefer not to immediately remove the hernial protrusion, but for many years to deal with its consequences and complications - to periodically treat inflammation, pain and swelling of the roots, which persistently arise again and again. And in this respect, the domestic patient resembles an unfortunate driver who, instead of finally changing a punctured tire, is forced to pump it up every half hour of driving. Only, unlike the driver, a patient who has been “treating” a hernia for a long time sometimes spends several times more money than the operation would cost.
Cervical hernia on MRI.
But even among the drugs for relieving swelling, back pain, and excess muscle tension, Neuromidin is not “listed.” However, it is sometimes prescribed for hernias, and is completely unjustified. The situation is aggravated by an unimaginably large number of sites that are written with stunning medical illiteracy. Because if there is a request “How to take Neuromidin for hernias,” then a helpful but illiterate article will immediately appear, which can even harm your health. How to take Neuromidin for hernias? Don't accept it at all. But first things first….
Interaction
Neuromidin® enhances the sedative effect in combination with CNS depressants.
The action and side effects are enhanced when used together with other cholinesterase inhibitors and m-cholinomimetic drugs. In patients with myasthenia gravis, the risk of developing a cholinergic crisis increases if Neuromidin® is used simultaneously with other cholinergic drugs.
The risk of developing bradycardia increases if β-blockers were used before starting treatment with Neuromidin®.
Neuromidin® can be used in combination with nootropic drugs.
Alcohol increases the side effects of the drug.
Reduces the inhibitory effect on neuromuscular transmission and the conduction of excitation along peripheral nerves by local anesthetics, aminoglycosides, and potassium chloride.
pharmachologic effect
Neuromidin belongs to the group of calcium channel blockers. Therefore, it helps reduce potassium levels in the body and, on the contrary, increases calcium in nerve endings. In addition, the drug prevents the effect of cholinesterase on neuromuscular fibers. Due to the occurrence of such processes, there is an increase in mediators in the body, namely adrenaline, serotonin, oxytocin and histamine.
The drug improves the transmission of nerve impulses in all areas of the muscles.
While taking this drug, there is a restoration of smooth muscle tone, synoptic connections and an improvement in mental activity, so new information is better and easier to remember.
The active component of the drug easily penetrates the bloodstream, and subsequently into the target organs.
Metabolism of drugs occurs in the liver. The highest concentration of the drug in the body occurs half an hour after use. The drug is excreted primarily through the excretory system.
